WILMINGTON, DE — A wave of profound grief has swept across the state of Delaware following a violent and chaotic active shooter incident that claimed the life of a dedicated public servant. On Tuesday afternoon, December 23, 2025, Matthew Tyler Snook, a veteran Delaware State Trooper, was killed in the line of duty during a confrontation with an armed gunman at the Delaware Division of Motor Vehicles (DMV) facility in Wilmington. The suspect, identified by authorities as 44-year-old Avery Young, also died at the scene after a rapid and heroic response by law enforcement.
The shooting, which occurred during the busy holiday week at the Hessler Boulevard facility, transformed a routine government office into a site of trauma and tragedy. As investigators work to piece together the motive behind the attack, the legacy of Matthew Tyler Snook is being honored by a community mourning a hero who made the ultimate sacrifice to protect the citizens he served.
The Active Shooter Crisis at the Wilmington DMV
The harrowing events began shortly before 2:00 p.m. at the Wilmington DMV, located on Hessler Boulevard in the Minquadale area of New Castle County. The facility was filled with residents attending to year-end motor vehicle services when the peace was shattered by the sound of gunfire. Initial 911 calls described a terrifying active shooter situation, with witnesses reporting that a gunman, later identified as Avery Young, had opened fire within the building.
The response from law enforcement was immediate and overwhelming. Officers from the Delaware State Police, New Castle County Police, and Wilmington Police Department, along with fire and emergency medical personnel, converged on the site within minutes. Command staff on the scene reported an “active threat,” and officers moved into the building under heavy fire to neutralize the shooter.
By 2:10 p.m., emergency radio communications indicated that two individuals were down. Paramedics rushed to the scene to administer life-saving measures, including CPR, to two primary trauma patients. One was the suspect, Avery Young, and the other was Delaware State Trooper Matthew Tyler Snook. Tragically, despite the best efforts of medical teams, both were later pronounced dead.
Remembering the Heroism of Matthew Tyler Snook
The loss of Matthew Tyler Snook has left an indelible mark on the Delaware State Police (DSP). Known among his peers as a “trooper’s trooper,” Snook was respected for his professionalism, his calm under pressure, and his unwavering commitment to the safety of Delaware residents. His death in the line of duty marks a somber chapter in the history of the department.
Governor Matt Meyer, addressing the state in a somber public statement, confirmed that Matthew Tyler Snook was killed while acting swiftly to secure the scene and protect civilians from further harm. “Trooper Snook was a hero who ran toward danger so that others could find safety,” Meyer said. “His bravery saved lives today, even as it cost him his own. Delaware stands in solidarity with his family and his brothers and sisters in blue.”
Flags across the state have been ordered to half-staff in honor of Matthew Tyler Snook. Behind the uniform, he was a member of the community, a colleague, and a friend whose absence will be felt deeply within the Minquadale area and beyond.
The Investigation into Suspect Avery Young
As the community mourns, the Delaware State Police and the FBI are leading a comprehensive investigation into the background of Avery Young. While Young’s identity was confirmed early in the factual record, the motive for his actions remains a central focus of the probe.
Investigators are currently examining Young’s digital footprint, financial records, and personal history to determine what led the 44-year-old to commit such a violent act at a public government facility. Preliminary reports have not yet established a direct link between Young and any DMV employees or the law enforcement officers present, raising the possibility of a targeted attack on the facility itself or a random act of violence.
The Delaware Department of Justice has dispatched senior prosecutors to Hessler Boulevard to assist with the legal aspects of the investigation. Attorney General Kathy Jennings is reportedly in direct communication with state police leadership to ensure that all resources are available to uncover the truth behind the actions of Avery Young.
Collateral Injuries and Medical Response at the Scene
While the focus remains on the fatalities, the scale of the incident resulted in several other injuries and medical emergencies. Authorities confirmed that a second Delaware State Trooper sustained a minor injury during the confrontation; however, this injury was not caused by gunfire. This officer was treated and is expected to recover.
Additionally, a 40-year-old woman was transported to a nearby hospital for treatment of minor, non-gunshot-related injuries sustained during the panic and evacuation of the building. The scene was one of extreme distress, with medical teams treating individuals for a variety of conditions, including one person who suffered a fall while fleeing the gunfire and another who experienced severe breathing difficulties amid the chaos. The rapid intervention of emergency medical services prevented these secondary incidents from escalating.
A Community Impacted: Closures and Redirected Services
The shooting has had an immediate and significant impact on local infrastructure and services. The Wilmington DMV on Hessler Boulevard remains closed until further notice, and a heavy police presence continues to occupy the grounds as forensic teams process the vast crime scene. All services at the facility have been suspended, and the Delaware Division of Motor Vehicles is directing residents to the Delaware City DMV for their needs.
Hessler Boulevard was closed for an extended period following the shooting, and major arteries, including portions of Route 13 south of Interstate 495, were temporarily shut down to allow for emergency vehicles and the secure transport of patients. Authorities are continuing to urge motorists and residents to avoid the area to allow the investigation into the death of Matthew Tyler Snook and the actions of Avery Young to proceed without interruption.
Statewide Support for Law Enforcement and the Snook Family
Tributes for Matthew Tyler Snook have poured in from law enforcement agencies across the country. From neighboring agencies in Maryland and Pennsylvania to federal partners, the message has been one of shared grief and profound respect. The Delaware State Police have established support systems for the Snook family and for the officers who were involved in the active shooter response.
“The bravery shown yesterday by our troopers and our partners was extraordinary,” said a spokesperson for the Department of Safety and Homeland Security. “We are heartbroken by the loss of Matthew Tyler Snook, but we are inspired by his legacy. We ask for the public’s continued prayers as we navigate this incredibly difficult time.”
The Delaware Department of Justice has asked for patience from the media and the public as the investigation continues. Officials emphasized that identifying details released at this stage are part of a preliminary factual record and that a final report on the incident may take weeks or months to complete.
The Legacy of Service and Sacrifice
As Delaware prepares for the funeral of Matthew Tyler Snook, the conversation has turned to the ongoing threats faced by law enforcement officers in the line of duty. The Wilmington DMV shooting is a sobering reminder of the volatility of public-facing roles and the suddenness with which tragedy can strike.
Matthew Tyler Snook will be remembered not just for the way he died, but for the way he lived—with honor, integrity, and a heart for service. For the people of Wilmington, his name will forever be associated with the lives he saved on that dark Tuesday afternoon. As the investigation into Avery Young continues, the state remains united in its gratitude for the man who wore the badge with such distinction.
